A former government nuclear bunker is sparking interest after auctioneers gave it a £300,000 starting price.
The bunker, near Twyford, Hants, is protected by 2ft thick concrete walls and six-inch deep steel doors.
The building was decommissioned in 1997 and was used by a computer security company who installed a kitchen and office space.
It is set into the hillside, two miles from the nearest shop.
Despite having no glass windows the auctioneers say it has stunning views to the north of the Hampshire Downs.
Rob Marchant, of Clive Emson auctioneers, said: "It would be an unbelievable home if you took the bank out and put in glass.
"The views are fantastic but you would have to convince local planners."
The interior has a musty smell and what was once a brick-barrelled reservoir has been converted into storage space.
It was originally built as a Victorian reservoir in 1905 before being closed in 1962 and transformed into a nuclear bunker in 1990.
